I try to make a series of How to make your loud PC to whisper quite, So start with the cooling method since most of the noise in the PC is come from the fan. Pretty sure you already have the idea of buying a new motherboard, a new CPU, a new case, and other gear stuff to obtain peace and quiet—you simply wanted to hush down the machine you currently own.

So this month, I’ve compiled an easy-to-use guide to reducing the noise levels of your rig’s various components. We’ll take a close look at each of your computer’s subsystems and identify its most common problems, then offer suggestions for reducing—if not eliminating—the noise. We’ll recommend bolt-on fixes and tweaks wherever possible, but in some cases, a hardware upgrade will be your best option.

1. CPU COOLING
The CPU is usually the hottest component in today’s PCs; as such, it typically requires the most extravagant—and often the noisiest—cooling apparatus. Reducing the amount of noise emanating from your CPU’s cooling system is a huge step toward muting your machine, so let’s examine this hotspot first.

As recommended of most Rig’s Modder, Cooler Master’s Hyper 6+ and Gigabyte’s G-Power—are exceptionally quiet while providing frigid temps. If you’re using a stock cooler or an aftermarket unit that sounds like a Hoover, upgrading to one of these silent wonders will bring joy to your ears. Both cost less than $50, so they’re an upgrade anyone can afford.

Water cooling is another way to reduce both CPU temps and overall noise levels. It takes care of the heat around your CPU, making a rear exhaust fan—a major source of noise—unnecessary in most cases. Unless you’re a serious overclocker, however, water cooling probably isn’t worth the time, money, and effort. You can usually achieve quietude with a massive heatsink/fan contraption.
